My advice is to leave well enough alone. Netbooks don't have a lot of storage space - nothing compared to a full sized lappy - and with Office installed, you probably don't have much room left anyway.

That said, if you're determined to move your music over, go to http://www.ilounge.com/ If it can be done, someone over there will know how.

(BTW, it's not just Windows. I can't hook up my iPod nano to my Mac and pull off the music. iPod/iTunes is proprietary even on Apple products!)
